Easy DIY herb-infused vinegars are a healthy addiction!
If using nettles, dill or other leafy herb; add last so that the spices will stay submerged in the vinegar.
NOTE: if the vinegar is topped up after each use, to ensure that the botanicals are not exposed to air, the vinegar will keep for up to 6 months.
(Confession: I have vinegars that are 2-3 years old, that are just fine)
